强安全性的三方口令认证密钥交换协议
Three-party Password-based Authenticated Key Exchange Protocol with Stronger Security
摘要
Abstract
Based on the protocol AugPAKE which has been proven security, this paper proposes a strong security Three-party Password-based Authenticated Key Exchange(3PAKE) protocol, which avoids using the server's public key to authenticate, and ensures the efficiency. It is proved to be secure against dictionary attacks, server leaked attacks and kinds of known attacks, and also applies key privacy to the server and forward security. The security of the protocol are proved based on Decisional Diffie-Hellman(DDH) problem and Strong Diffie-Hellman(SDH) problem in random oracle model.关键词
